HENRY SIMPSON, OF ELMIRA, NEXV YORK.

WOODWORKlNG-TOOL.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed August 3, 1905. Serial No. 272,570.

To a, whom it may concern:

Be it known that I, HENRY SmirsoN, acitizen of the United States,residing at Elmira, in the county of Chemung and State of New York, haveinvented certain new and useful Improvements in "oodworking-Tools, ofwhich the following is a specification.

My present invention relates to an improved woodworking-tool, theconstruction and advantages of which will be hereinafter set forth,reference being had to the annexed drawings, wherein- Figure l is a sideelevation of the tool; Fig. 2, a transverse sectional view on the line 22 of Fig. 1; and Fig. 3, a perspective view, partly broken away, of oneof the members.

The object of the invention is to provide a combined reamer or cutterand work-support, the tool being especially useful in the manufacture ofwood pipe and like hollow wooden articles.

Nood pipes when made of staves, as is now the usual practice, are moreor less rough upontheir inner faces when the staves are iirst assembled,and this unevenness must be removed.

The tool herein shown and described is designed to ream out the pipe,thereby making its bore even and true, and likewise to act as awork-support for the pipe while it is undergoing further treatmentas,for instance, when the end is being turned down to form the tenon orsocket.

Referring to the drawings, A denotes the main body of the tool, having athreaded hub B. The body is formed upon one side with a series ofradially-disposed ways in which are seated the stems U of theradially-adjustable shoes D. Stems C, as will be noted upon reference toFig. 3, are provided with elongated openings or slots E, through whichare passed screws F, the screws passing into the body A and serving tosecure the shoes in their adjusted position. The outer face of each shoeis convex, the radius of its curve by preference being substantially thesame as that of the outer face of the body portion intermediate theshoes. As will be noted upon reference to Figs. 1 and 3, the under faceof the shoe is flat, so that when the shoe, or radiall vmovablc member,as it may be termed, is moved inwardly to the full extent it rests upona corresponding flat face formed upon the periphery of the body.

Each adjustable shoe or member is provided with a roller (i, mounted ina recess formed in the body of the shoe, the recess cutting into orthrough the convex face of the shoe, and thereby permitting the rollerto extend slightly beyond the periphery of the shoe. The recess is ofsuch size that the roller may turn freely upon its supporting pin oraxle H.

The body is provided with aseries of transverse openings or recesses Iat its periphery, there being one of such recesses adjacent to each ofthe rzulially-disposed ways in which the adjustable shoes are mounted. Aseries of cutter blades or knives J is adjustably mounted upon the body,preferably upon the side opposite to that upon which the ways areformed, the ends of the knives overlying the recesses l. \Vhen the shoesare retracted and the knives protruded, the tool may be used as a reameror cutter-head to bore out the pipe and produce an even surface therein.hen the knives are retracted and the shoes protruded, the tool may beused as a work-support, the rollers bearing against the inner face ofthe pipe. The pipe will be firmly held up to any tool which may beacting thereon, the curvature and long bearing-faces of the shoespreventing any wabbling which the rollers might not possibly prevent.

Having thus described my invention, what I claim is 1. A tool comprisinga body portion; a series of radially adjustable shoes arranged about itsperiphery, each shoe being provided with a roller; and a series ofcutters also carried by the body portion.

2. A tool comprising a body portion; a series of radially-adjustableshoes carried thereby; a roller mounted in each of said shoes, theperiphery of the roller extending slightly beyond the periphery of theshoe; and a series of adjustable cutters also carried by the bodyportion.

3. A tool comprising a body portion; a series of rollers arranged aroundits periphery; and a series of knives carried by the body, the knivesand rollers being relatively adjustable, whereby the tool maybe used asa work-support or cutter-head, substantially as described.

A. A tool comprising a body portion; a series of shoes radiallyadjustable thereon, the outer face of each shoe being curved; a rollercarried by each shoe, the periphery of the roller extending beyond thecurved face of the shoe: and a series of adjustable knives carried bythe body portion.

5. A tool comprising a body portion provided with a series of recessesabout its periphery; a series of knives carried thereby, the r Intestimony whereof I have signed my name outer ends of the knivesoverlying the reto this specification in the presence of two subcesses;a series of radially-adjustable shoes scribing witnesses.
